Service and limitations

This is a supplied-state mathematical API, not investment advice, custody or transaction execution. You are responsible for input state, asset identity, decimals and freshness. V2 supports constant-product quotes and connected routes. V3 quotes stay inside one supplied liquidity interval and reject tick crossings. Bounded arbitrage optimization does not guarantee a global optimum. Availability and market execution are not guaranteed.

Subscription and cancellation

Paid plans are monthly subscriptions in USD, automatically renewed until canceled. The price and any applicable tax are shown before you submit payment. Card issuer exchange charges may apply. Cancel through Dashboard → Manage subscription before renewal; access normally continues until the current paid period ends. Failed or canceled subscriptions can lose paid access. Plan upgrades/downgrades and any proration are shown in the billing portal.

Refunds and use

Payments are normally non-refundable. Service failures or other problems may qualify for an exception; contact support with the affected period and request identifiers. Mandatory statutory remedies remain available. Do not abuse the service, attempt unauthorized access or disclose your API key. Usage limits and supported calculation scope are described in Pricing and Docs. Invalid calculation requests after quota reservation may consume units.

We may update these terms with notice on this page. Changes affecting existing paid commitments remain subject to applicable law.
